summer of 13
tanks for fish and plants
i made these things with the same principals and practices i use for making solar thermal tanks. they are flexible in size and shape and can be built in tight spaces
the big ones are alot stronger if you build them upside down and then flip. this way you can really secure the bottom plate to the ply
fill those cavities with some insulation. put some under while your at it
overlap those wall corners with plywood. put some more insulation down then the bladder
unfold it like a present and go.
i put a bulkhead in, but have not used it yet.
the uni makes things adjustable.
this is the drainback tank for a closed loop glycol system
glycol is pumped through radient tubing in the fish tank, then up through a thermal panel on the side of the greenhouse and back to the 10 gal rez
heres 3 beds above the tank. 2 are filled with lava rock and 1 here shows the bell siphon that goes through the bottom via a bulkhead
here was my first grow, just gettin goin
the thing was a bitch to maintain in the summer, so i decided to put a grow bed outside, but utilize the fish tank in the greenhouse. this was Dave Tucks truck bed
worked out pretty good size wise, this bed was close to 3 of the ones inside. had to raise it enough to get a drainback back to the tank
again, a bladder tank filled with lava rock and a bell siphon
